Arbovirus studies of bats from Zulia State serological survey for venezuelan: eastern and western encephalitis virus antibodies february 1976 / Estudio sobre arbovirus en murciélagos del Estado Zulia encuesta serológica para determinar anticuerpos contra encefalitis venezolana: encefalitis del este y encefalitis del oeste febrero de 1976

One hundred and forty five bats of 13 species collected during february 1976 at three sites in the State of Zulia, Venezuela, were negative for hemagglutination-inhibition (HI) and neutralization antibodies to venezuelan encephalitis virus. One hundred and thirty seven of these were also negative for HI antibodies to both Eastern and Western encephalitis viruses. Due to small series for most species in the sample, negative results are difficult to interpret

Actividad del virus de la encefalitis equina venezolana en el norte de Colombia, abril y mayo de 1983 / Venezuelan equine encephalitis virus activity in northern Colombia during April and May 1983

Venezuelan equine encephaltis (VEE) virus was isolated from sentinel hamsters exposed in the Rio de Oro region of Colombia, in the Lake Maracaibo drainage área near the border with Venezuela, in 1983-13 years after the first strain was isolated from the region near Tibu. Hydroxylapatite elution profiles of three isolates from the Rio de Oro region were typical of enzootic strains. Relative abundance data and past isolations suggest that culex (Melanoconion) pedroi is a probable enxootic vector at this focus. The virus was no isolated from forests near Santa Marta and Magangue in the Rio Magdalena drainage área in 1983-9 and 16 years, respectively, after the last previous isolations in those áreas. However, equine animals 2 to 10 years of age and humans 25 to 67 years of age living near the Magangue field study área were positive for VEE virus-specific neutralizing antibodies

Manadas de caballos como centinelas para detectar la actividad del virus de la encefalitis equina venezolana en Nicaragua, 1977. / Herds of horses as sentinels for detection of the activity of the equine encephalitis virus in Nicaragua, 1977

Los sueros tomados de 93 caballos en ranchos nicaraguenses y las pruebas serologicas que se practicaron para detectar en ellos la presencia de anticuerpos del virus de la encefalitis equina venezolana (EEV), muestran que tales caballos pueden servir de centinelas baratos y eficaces para detectar la actividad de ese virus
